You don't need to worry about drivers for configuring monitors. All the Xserver needs to know is hte frequency range and resolution that the monitor can handle and it will work everything else out itself.

In general X is pretty good at supporting CRTs. But you might have to find some documentation about the characteristics of your particular monitor to get the best out of it.

You can manually edit /etc/X11/xorg.conf and enter the parameters you need into the Monitor, Device, and Screen sections as needed. You would need to restart your X server to see the results. I am pasting what is in mine below.

The monitor I have is a flat-screen LCD monitor, but I had to do this manually for FC2 and FC3. FC4 did detect the monitor properly, but I was prepared to manually edit it again if I had needed to. In any case, I still needed to edit it to be able to use the NVIDIA driver.

Thanks a lot, I just migrate from Windows, so it is a bit uncomfortable with the command line approach, but I will work hard for it because I really like it. And I think it has better performance than Windows!!
